Photography ... astronomy ... art ... design ... technology
(... and the odd rant)

All of these make my world go 'round, to some extent, and they will all be found here at some time or other. Some of the photography can be purchased from my Redbubble site. I can also be found at Tempus Fugit (no longer being updated).

The Dictionary Effect

One of the perils of life online is distraction. You want some information and go looking for it; you might or might not find what you want, but you will almost certainly find other things that you don't want either, but which are very tempting. You know how it goes: one query spawns five links worth looking at; each of those leads to five others, and so on. Within minutes, you can forget what you went in search of, and spend an obscene and distressing amount of time looking elsewhere at undeniably fascinating sites. Then, when you try to retrace your steps from the final page you dare look at, you will find it's next to impossible.

I always used to have this problem with dictionaries (still do), as they can be similarly engaging with serendipitous disovery. Dictionaries are safer though - each new link takes but seconds to read, and probably only leads you on a single trail, instead of an almost infinitely diverging set of possibilities.

xkcd expresses it thus...

Bad dreams

For many years, I worked in an environment where procedures had to be followed very precisely, processes had to be rigorously tested and monitored, and where cleanliness (the workplace, not personal) was of paramount importance. The fact that I grew tired, not so much of the need for such tight control, but of the monotony of it all, meant that I baled out when the opportunity arose. About a couple of years afterwards, I returned to a similar role on a temporary basis, which merely served to confirm that I was right to leave in the first place.

Ever since that time, 12 years ago, I have had occasional unwelcome dreams that I am back in the old place, finding that all is not as it should be; the clean room is filthy, a vital part of the processing chain has not been turned on, I have forgotten to attend to a task until far too late, or I am simply back in purgatory, doing a job that has lost all of its appeal. Whatever the circumstance, it is usually a minor disaster, and fills me with feelings of utter dread.

The other night though, came a new variation: the entire facility had been dismantled, leaving only a leaky water supply. Does this mean that I have finally laid the ghost? Will I be able to sleep in peace from now on? I live in hope. Or perhaps I will be like Tantalus, where the waters recede every time I try to mop them up, and flow again when my back is turned. That I could cope with!

You can't do nuthin'

We've had a fair bit of rain lately (he says, using traditional British understatement, since Northern NSW and parts of Qld have copped enough to float the navy). In a land enduring a protracted period of drough, it is however, generally welcome. Not all of it has fallen in the right places though, and hereabouts - which has been a lush green for a long time now - this particular natural bounty is somewhat surplus to requirements. Further than that: being school holidays, it is less than welcome as the clouds dump on us for the umpteenth day. Too bad, but we'll survive.

However, I hopped on a bus recently, and the driver greeted an acquaintance with "You can't do nuthin'," as she bemoaned the continuing precipitation. I had to wonder how people get by, with such a limiting outlook. The good citizens of Coffs Harbour are demonstrably doing a wide range of things. Few of them, I grant you, are connected with chasing a ball about, pursuing piscean prey, or lying on a golden beach, cultivating melanoma, but that still leaves many other possibilities. In a few days' time, the same people will be complaining that it's too hot and humid.

PFTHRRPPPPP!!!

Obsession

I've been away, speaking figuratively. Same desk, same PC, different bit of cyberspace. RedBubble, it seems, is somewhat addictive. However, I do have a life beyond it, and part of that life encompasses astronomy from time to time.

In doing a bit of research for a talk last week, I came across
Galazy Zoo. This is an online project that encourages people to assist with the massive task of classifying distant galaxies. As the site says, it's a: "project which harnesses the power of the internet - and your brain - to classify a million galaxies. By taking part, you'll not only be contributing to scientific research, but you'll view parts of the Universe that literally no-one has ever seen before and get a sense of the glorious diversity of galaxies that pepper the sky."

Well, I just went back to that site to look a bit further, and ended up registering. That process led me very quickly through the tutorial & test, and straight on to the work itself. No fuss, no ceremony, no tedious application or PhD thesis, just lots of pictures, as fast as I could work through them. And therein, I think, may lie the success of this project: as soon as you've done one, another image appears. Well, you can't possibly leave that one, so you do it. Then, there's another - which will only take a second or 2 - and then ... and so on. Oh, go on, just one more, it might be an interesting one. Here's a screen grab:


And so, obsession rears its ugly head once more. Have a go, you might enjoy it!

Lovely bubbly

I'm a RedBubbler now; discovered the site a few days ago, and have just started uploading images. I've been looking for an online outlet for a while, and this seems to be a good one. Check out the images and leave a comment.

Twinkle, twinkle

Sitting in the car tonight, waiting for my daughter, I opened the window and looked skyward. A beautiful night, warm, with as many stars as one would expect, this close to a sizeable regional town, and a crescent moon high in the west. A typical scene, yes? Well, it is here, Down Under (notwithstanding the wet season's first substantial cloud-bounty). However, I was taken back to my first experience of Australian skies, after first arriving here from Scotland 20 years ago. I was captivated. Not surprising, giving that I'd left a freezing northern land in January, complete with snow-turned-to-ice on the ground, and embarked on a delightful sojourn (it was supposed to be work, but was too much fun for that to be relevant) to the sub-tropical antipodes.

From 0° C to 40° C in the space of about 5 days, was quite a change. Temperature is just physics though; it required some adjustment, but it was what it was: hotter than I'd ever imagined. The sky however, was something else. Seeing Sirius nearly overhead, its brightness undimmed by the low altitude of a Scottish viewpoint, was the first thing of note. The second remarkable thing was that this scene was to be observed night after night - such that, after 2 months of unremitting sunshine and blue Rayleigh scattering, I was delighted to see a cloudy sky for a change. Anyone accustomed only to the perpetually grey skies of Britain would probably find that hard to imagine...

Back to tonight: it's easy to become blasé about the beauty of the sky, when it's always there, being ... beautiful. And even as an amateur astronomer of some 35-40 years, I am as affected by that as anyone else, and need to take a longer second look sometimes. Having said all that, what appeals so much about the night sky here - at least, between spring and autumn - is the fact that the whole experience is so damed comfortable. I don't have to put on 3 inches of insulation, before heading out to discover that it has now clouded over. There is such a sense of blissful relaxation to be had, looking at distant beacons gliding ever so slowly overhead, while crickets, cicadas etc sing their song.

I have to admit though: I'd exchange a few of these balmy, almost unchanging nights for a few displays of aurora under a crisp heaven with fiercely-twinkling stars. Of all the sights in nature, there can be few as awesome as the northern (or southern) lights. With that thought, here's a pic taken some years ago: a green rayed band over the orange glow of Edinburgh. It's a sight I will never tire of.

Hydrangea

It seems I have a minor - but possibly growing - obsession with a hydrangea. We have one in a large pot on the back verandah, which is enjoying exuberant growth. It was somewhat abused a couple of years ago, being fairly sunburned and drought-afflicted. After being moved to a better spot and being treated more tenderly though, it is thriving once again.

I am drawn towards it with camera in hand; there's something about the leaf shape and texture that is so appealing: well-defined veins and bold serrations, with a satisfying sheen on at least some of the leaves. There is also a slightly unruly quality to the leaves, with unexpected twists and curls. The pink flowers, pretty though they are, don't interest me so much; possibly because I am inclined to render the images in monochrome, and they don't present enough of a graphic form to be worthwhile. Maybe I should take another look, and see if I can create a pleasing image from them as well. I might surprise myself.

Look what I found

I have spent several days, on and off, tidying my home office. It was in desperate need of it, for 2 reasons: 1, I am perpetually under-organised; 2, I have just moved the contents of an external office into the home, which made the floor disappear. Today was substantially the culmination of the process, in that it now looks organised, and ready for business. Indeed, SWMBO came in a few hours ago and said "what's that?"
"It's a piece of MDF", I replied.
"No, that," she insisted, waving her hand over the empty space (specifically, a desktop covered with said MDF).
Ah, yes, empty space. I have been the proud possessor of such a thing from time to time, but it invariably fills up with all manner of detritus as soon as my back is turned.

I realised some time ago that paper is the bane of my life. Copy paper, printed paper, brochures, forms, magazines, interesting snippets, etc etc... Once I had come to that realisation, I felt I had at least taken a step forward. Realising it was one thing though, dealing with it was another.

This time it will be different. I will be the master, and paper will be my servant; on call for when I need it, and despatched when I don't. It will be ephemeral, discarded on a whim, and only retained if it will serve a purpose. This will begin tomorrow, when my new assistant starts work ... a ruthlessly efficient filing system, coupled with In/Out trays that actually function as they are supposed to.

Tomorrow is a bright new morn...

Fascinating books (that I haven't yet read)

I like to catch the Book Show on ABC Radio National, when I can. It's a usually a welcome retreat from daily life. Today I listened while waiting in the car outside Spotlight, as SWMBO picked up supplies for a current magazine project. I'm not, I confess, a real outdoor person, although I do like the idea of being so. Today's guest, Robert MacFarlane, was discussing his new book The Wild Places. Not only was the subject of interest, but Robert was a pleasantly modest, gracious and engaging interviewee. His brief tales of 'night walking' along a ridge of hard snow and ice by moonlight, and the holloways of Dorset – among others – were quite thought-provoking. The transcript is here. A New Statesman review of the book is here.

14 May 2008 update: the current issue of Orion Magazine has an article here.

Another transcript that sounds interesting is from Monday's show, which included The history of virginity with Hanne Blank. Dare I look forward to The history of the loss of virginity...?

The tangled web

Dictionaries & the WWW: I love how you can go looking for one thing, and end up somewhere totally different, if you're of a mind to follow the path. It kind of fits in with the sentiment that we should "chase wild geese - that's what they're for."

This evening, I went looking for the history behind the ISO 'A' format paper sizes, following a discussion with a local artist today. I felt it was probably had some ancient British or German origin, which just happened to translate to the strange 297x210mm for A4 (etc). Turns out it is connected with old German & French thoughts on the merit of a format in which the ratio of the 2 sides of the sheet is 1:[square root of 2]. This allows a sheet to be folded in 2, and still be the same shape. Markus Kuhn says this:

"One of the oldest written records regarding the sqrt(2) aspect ratio for paper sizes is a letter that the physics professor Georg Christoph Lichtenberg (University of Göttingen, Germany, 1742-1799) wrote 1786-10-25 to Johann Beckmann. In it, Lichtenberg explains the practical and aesthetic advantages of the sqrt(2) aspect ratio, and of his discovery that paper with that aspect ratio was commonly available at the time. (There are also suggestions that the task to find a paper format that is similar to itself after being cut in half appeared as a question in mathematics exams as early as 1755.)"

However, James wondered how they arrived at an odd number like 297mm, which doesn't multiply to a nice round number. The answer is simple, and logical - from a metric viewpoint: A0 is one square metre, or very nearly so (with the 1:[square root of 2] ratio). Everything follows from there. Here endeth the lesson.

The point of this is that, having gone in search of old technology, I stumbled across someting very much of the present, a Flash animation. The front page of this site has a mesmeric animated mandala, and the succeeding page has an equally fascinating linear array. Both are affected by movement of the cursor with the the bounds of the graphic. Have a go: mothteeth.com
